Compare three vendor quotes with Claude or ChatGPT

Updated

The board wants a table for the lift, the paint or the waterproofing. Each vendor sends a different PDF.

Claude and ChatGPT read several PDFs in the same chat. The table comes from there. The meeting still chooses the vendor.

Step 1. Ask for the missing fact in writing

Before you upload the files, check that each quote states:

  • Scope: which area, which equipment, which floors.
  • Schedule.
  • Warranty, in months and over what.
  • What is excluded. For example scaffolding, edges or tax.
  • Payment terms.

Step 2. If a fact is missing, write to the vendor

Send this message and wait for a written reply. A voice note does not go in the table.

Hola. Soy de la administración del Edificio Rivera. Para comparar tu presupuesto con los otros dos, necesito por escrito: alcance, plazo, garantía, qué no incluye, forma de pago y si el precio lleva IVA. Si un dato no aplica, dímelo. No inventes nada que no esté en tu oferta.

Step 3. Upload the three PDFs and paste the request

Open Claude or ChatGPT.

Attach the three PDFs in the same chat. Wait until all three have finished uploading.

Copy the request. Change the roof job for today's job.

Te adjunto tres presupuestos en PDF de la misma obra: impermeabilización de la azotea del Edificio Rivera. Es un edificio de ejemplo.

Arma una tabla con las mismas filas para los tres:
- precio total
- qué incluye
- qué no incluye
- plazo
- garantía
- forma de pago
- IVA

No elijas un ganador. Si un dato no está en el archivo, escribe "no consta". No conviertas unidades ni estimes metros. No inventes datos. Indica cualquier información que falte para poder usar la tabla.

Step 4. Check the table against the PDFs

Ask the chat: are all three quoting the same area?

Also ask whether one price is before tax and another includes tax.

Open each PDF and find the number that appears in the table. If it is not there, delete it from the table.

Below is a sample CSV with round numbers for a made-up building. It shows the rows. Do not present it as a real quote.

Step 5. Take the table to the meeting

Write above the table: «Comparison of the PDFs received. The choice belongs to the meeting.»

Bring the three files, not only the table.

After the choice, write to the vendor, set the day and tell the owners.

When you still have to write to the vendor

The table compares. The work after that is the message: ask for the visit, confirm the day and tell the building.

Eloria talks with vendors and residents on WhatsApp and by email, at any hour, using that building's instructions.

It always replies to the resident. If a vendor must be chosen or a spend approved, it writes to you with the context. The resident still gets an answer.

It follows up with the vendor and with the building. You see every conversation in a panel.

If you set office hours in the panel, non-urgent items wait until you are available. Urgent items reach you right away.

In the busiest buildings, 1 in 3 resident messages arrives at night, early in the morning or on weekends. Eloria answers at any hour: half get a reply in 12 seconds or less.

It works building by building. If you manage several, each job stays with its building.
